WISCONSIN FLOW REPORT

Last Updated: December 4, 2025

Wisconsin's river conditions exhibit a diverse range of streamflow trends that are of significant interest to river enthusiasts, environmentalists, and local communities. A recent analysis of the state's streamflow data reveals several anomalies and patterns. The majority of rivers are currently reporting streamflows below their normal levels, with noteworthy decreases in popular rivers such as the Fox River at Oshkosh, which shows a dramatic increase in streamflow change over the last 24 hours by 294.98 cubic feet per second (cfs) but is still 81.63% below the normal flow, posing potential concerns for both recreational use and local ecology. Conversely, the St. Croix River near Danbury presents an increase in streamflow by 112.9 cfs, sitting at 12.4% above normal levels, indicating healthier conditions which could be favorable for whitewater activities.

In particular, hydrological data indicates the Wisconsin River at Wisconsin Rapids is experiencing a significant flow deficit, operating at 53.98% below normal with a streamflow of 1670 cfs and a gage height of 2.71 feet, raising concerns for potential flow droughts that could impact not only recreational water activities but also water supply and wildlife in the area. On the other hand, the Menominee River near Mc Allister, despite experiencing a slight decrease over the last 24 hours, still maintains a robust streamflow of 2220 cfs, though it is 31.21% below the expected level, potentially affecting cities like Mc Allister. With several rivers, such as the Pecatonica and the Kickapoo, also reporting lower than average streamflows, stakeholders are advised to monitor changing conditions, particularly as we approach seasonal shifts that could exacerbate or alleviate current trends. The variation in streamflow emphasizes the need for adaptive water management and conservation strategies, as well as vigilance among water enthusiasts planning activities on Wisconsin's rivers.
